John is starting a roofing business. He will need to buy a truck and some supplies to get the business going, the truck cost $13
JulijaS [17]
John will only need to buy the truck once, so that is $13,000. 
27,000-13,000=14,000 
If each project costs 1,000, he can complete 14 jobs.

Find the value of the following expression:
Illusion [34]
Ok, so first you solve whatever is in the parentheses.
(28 • 5-5 • 190)-2•228
28• 5 = 140
Then 5 •190 = 950
Then multiply 950 • 140 = 133,000
Then it should look like this:
133,000-2•228
Multiply 2 • 228 = 456
Then subtract 456 from 133,000.
The answer should come out to 132,544.
